She’s only fifteen years old, but she certainly didn’t look it on Wednesday.

As Kylie Jenner attended the After Earth premiere at the Ziegfeld Theater in New York City, the Keeping Up With The Kardashians star dressed older than her tender years in a revealing ensemble.

Looking more like something one of her older sisters would wear, the brunette chose a zip-up, black crop top with a high-waisted, assymetical black skirt.

She teamed the pieces with a pair of black, mid-calf, open-toe cages boots, and carried around a black Celine tote – a designer handbag that many girls can only dream of owning.

Opting for a dramatic make-up look, Kylie amped up her eyes with cat-eye liner and lengthening mascara, as she pronounced her lips with a bright shade of fuchsia.

Showing off her lustrous locks, the reality star had her ombre hair styled in relaxed curls, flowing to her waist.

She was definitely looking forward to the premiere and supporting her good friend Jaden Smith, because she retweeted her friend Pia Mia’s post: ‘”@princesspiamia: Can’t wait to see #AfterEarth tonight at the New York premiere! @KylieJenner ❤ So proud of you @officialjaden, scopes.” :)’

And after the show, the younger sister of Khloe Kardashian, Kourtney Kardashian, Kim Kardashian, and Kendall Jenner, gushed about how great the flick was.

‘AE was amazing!’ she tweeted.

Earlier in the day, Kylie and Jayden showed off their youthful sides during an outing in Manhattan.

The 14-year-old film star was seen in an Iron Man suit, with Kylie as his accomplice in a leopard print dress, heeled boots and a full face of make-up.

The pair were spotted leaving the very adult Nobu 57 restaurant in New York , with Jaden  dressed in a copycat of the shiny suit that Robert Downey Jr.’s character wears in the action series.

Jaden’s suit was not too far off from the vibe of his film After Earth, a sci-fi adventure.

In the film, he plays Kitai Raige alongside his father Will Smith, who plays his father Cypher in the film.

The two are stranded on Earth, 1,000 years after events forced humanity’s escape, and Kitai must embark on a perilous journey to signal for help after his father becomes injured.
